Seawall Repair Near Me

We love how the long coastline of southwest Florida offers homeowners beautiful, soothing vistas right at the water’s edge, in locations including Tampa, Naples, Clearwater, St. Petersburg, Naples, Cape Coral, and Fort Myers, FL. Preserving these waterside properties from ongoing sea erosion or stormy weather often depends on a sound, protective seawall.

In our business, we come across a variety of seawall materials, the most common being reinforced concrete because of its longevity. We know firsthand, however, that even concrete is not invincible against the forces of nature. These walls require regular vigilance to detect common signs of wear such as cracks, cap failure or berm loss. If left unchecked, these and other problems will lead to costly wall failures in the future.

Signs of Seawall Failures

As waves and tides encounter a seawall, it is subject to cyclic pressures and the possibility of water and soil flow through joints, holes, cracks or other defects that gradually reduce the wall’s and backing soils’ structural integrity. Florida’s heavy rains and storms only exacerbate any such defects. A variety of symptoms, including seawall leaning or crumbling  cap or wall cracks, bulging or sinkholes may be present.

Naturally, if such signs of deterioration exist, we suggest that you deal with them as early as possible to avoid the extreme expense, environmental damage and inconvenience of total or partial seawall replacement. A do it yourself method for seawall repair is not a viable option because you can do more harm than good. Read on to see the professional way to solve seawall problems quickly and affordably.

Comparing Seawall Repair Options

Fortunately, there are several economical approaches to how to repair a concrete seawall that seawall repair specialists utilize. One of the most cost-effective methods of how to reinforce a seawall employs the use of polyurethane grout, which evades several disadvantages of using the outdated technique of cement grouting:

  • Cement grouting requires a significant amount of machinery and labor, which has the side effect of creating a bigger mess on your property.
  • Cement grout can increase the weight of the wall structure, which risks the wall sinking.
  • Shrinking and degrading is also a problem specifically related to cement grouting.

Using an advanced polyurethane resin, on the other hand, has none of the flaws above while providing a more lasting solution to remedying seawall cracks, seawall leaning, and soil voids:

  • We install chemical grout with a minimum of disturbance to your property caused by excessive equipment or messy materials.
  • The process of polyurethane grout repair is far quicker than cement grouting and returns your property to use within hours instead of days or weeks.
  • This repair approach is especially apt at quickly eliminating leaks up to thousands of gallons per minute.
  • Polyurethane grout repair is also absolutely environmentally safe.

As you can see, the use of chemical grouting is a clear winner over cement grouting for both the owner’s property and their pocketbook.

Seawall Repair Methods

Let’s investigate some of the details of our seawall repair methods so that you can see why we strongly recommend its use for erosion behind seawalls.

Single Component Solution or Two-Component Solution

Our polyurethane resin (chemical grout) is ready to go in an instant, which contributes to an efficient installation process. Our single-component solution densifies the soil while our two-component solution expands and lifts concrete. Some repairs can have a combination of both solutions utilized in the repair. The preferred method for seawall repair is to utilize a permeation grout that will densify the soil and permanently bond and embed itself into the soil.

Low Viscosity for Excellent Penetration

Chemical grouting is especially good at penetrating the thinnest cracks and voids due to its exceptionally low viscosity, which is measured with a unit called a centipoise. Our resins are typically in the range of 110 to 150 cps, which is comparable to the viscosity of corn or maple syrup.

Customizable Set Time

Depending on the specific concrete repair job, we can adjust the grout set time using a catalyst. In cases where voids are large or there is leakage, we prefer a rapid set time. Often for concrete leveling, however, a longer set time is desirable so that the grout can further permeate the soil for a lasting repair.

Exceptional for Filling Voids

Our chemical grout expands when it comes into contact with soil moisture or water, which furthers its ability to completely fill voids. Once it sets, of course, it is completely impermeable to moisture in part due to the closed-cell structure it forms. This property is also important when using poly-resin for uniformly lifting concrete.

Highly Adhesive

Not only does our chemical grout thoroughly fill voids or permeate sandy soil to solidify it, but its adhesive properties also guarantee that it permanently bonds with its surroundings, unlike cement grout. It is designed to last a lifetime and beyond.

Environmentally Sound

We care about your environmental safety, which is why we only use phthalate-free polyurethane resins for concrete repair. Unfortunately, some contractors still use grouting resins manufactured outside the U.S. that contain this known ocean pollutant. In fact, our resins are NSF certified for cases where it may contact drinking water.

No Heavy Equipment Needed

With polyjacking there is no reason for a lot of heavy equipment that most people associate with mudjacking. There will not be the same damage to the surrounding landscape. Even during the actual chemical grout application, the job site will be cleaner. In addition to the neatness factor, there is the speed. Raising concrete with polyurethane grout enables the property owner to use the walkway, driveway, or other surfaces right away. With mud, there is a lengthy curing time that requires foot and vehicle traffic to stay away.

Perhaps the most exciting difference is the fact that chemical grout is hydrophobic. Wet conditions and nearby water leaks will not impede its repair powers. It does not fall victim to liquid damage. The same is not true for mud. Instead of creating a barrier for the moisture, it attracts it and reacts with the water, which results in subsequent shifts of previously leveled concrete. Because a concrete lift should last for a long time, the foam method wins hands down.

Speaking of leaks, consider that chemical grouting is an expert method for filling wet voids without having to trench through the area. It can waterproof the area, and there is no need to dig holes to reach the problem areas from the exterior.

Further Repair Uses for Chemical Grout

Besides being an efficient, clean and durable solution for seawall repair, we prefer chemical grouting for a number of additional repair and remediation applications.

It is especially useful for a process known as polyjacking used in raising concrete driveways, walkways or a foundation. Polyjacking enables precision lifts to align adjacent slabs or to level a foundation. The solution is permanent and will not settle back afterward.

We also apply our poly grouting techniques to stabilizing soils to prevent soil subsidence or when repairing sinkholes. The grout’s properties are also ideal when contaminated soils require encapsulation to keep them from spreading.

State-of-the-Art, Durable Seawall, and Concrete Repair

For over 18 years, as seawall professionals of Florida, we have applied our advanced processes for correcting seawall leaning, raising concrete, filling voids, concrete leveling, etc. across the Florida southwest coast using the superior technology of chemical grouting. It has so many advantages over excavation or cement grouting methods, including requiring less time and minimizing impact to the environment and property. It is also proven to provide the most lasting, economical solution in the vast majority of cases.

From Tampa, FL to Miami and all places in between, if you have a seawall, we strongly recommend you keep an eye on it so you can nip in the bud any deterioration of this vital structure as early as possible.
